Abstract
An automation technology field device, comprising a radio module, wherein the radio module is configured such that it forms at least one first radio channel and one second radio channel, wherein the first radio channel is configured for a reading access and the second radio channel for a writing access to the field device, characterized in that the second radio channel is deactivated in a basic state of the field device and the field device has a switching element at least partially realized as hardware, wherein the switching element is configured such that the second radio channel can be activated.

An automation technology field device, comprising a radio module, wherein the radio module is configured such that it forms at least one first radio channel and one second radio channel, wherein the first radio channel is configured for a reading access and the second radio channel for a writing access to the field device, wherein the second radio channel is deactivated in a basic state of the field device and the field device has a switching element at least partially realized as hardware, wherein the switching element is configured such that the second radio channel can be activated.
The automation technology field device according to claim 41, wherein the operating member is configured and arranged such that an actuation is possible only when the radio module is removed from the field device.
A modular field device system for building field devices, comprising
- a plurality of housings,
- a plurality of sensors,
- a plurality of electronics modules that can be connected to the sensors, and
- a plurality of display and/or operating modules that can be connected to the electronics modules, wherein the field device system has at least one display and/or operating module with a radio module for wireless communication with at least one further unit, wherein the radio module forms at least one first radio channel and one second radio channel, wherein the first radio channel is configured for a reading access and the second radio channel for a writing access to the field device wherein the display and/or operating module has a switching element at least partially realized as hardware, wherein the switching element is configured such that the writing access to the field device can be activated.
